106 1.5D Head Gasket

Post by irvined »

Hello,
I beleive the head gasket is blown in my 106, Got a quote to replace the gasket at 300, the garage, not a dealer, but reputable peugeot specialist, advised me that the cam belt tensioner is fairly easy to set .(This is the bit the haynes manual warns to be careful with)
I'm probably going to do this myself, I'm going to buy a new cam belt, and head gasket set, is there anything else I should buy? Do I need new head bolts?
Has anybody else done this by themself? if so, any advice greatly welcome.
Thanks
David

It'll be worth you doing the auxiliary drive belt at the same time.
Also as you'll be working in the general area, the water pump is a very strong candidate for replacement at the same time.
However - do you know why your gasket went? If there is an underlying problem (like a partially blocked radiator) they you'll be doing the head gasket again soon unless you deal with the underlying problem.

Hello,
Thanks for the response, I'm not sure of the underlying cause, the car has just done 115k, at the start of the year it had a leaky radiator and overheated and its had a few other problems since then, I suspect the radiator leak was the trigger, although it seems to be a really common problem around this milleage. I initially thought the injection pump was on the way out as its been getting harder to start, but once it started smoking it became more obvious what was causing it.
Whilst im in the area im going to replace the cam belt, and the pump as its not something i want to do again any time soon.
So far on the list of things to get are:
Head Gasket Set
Replacement Head Bolts
Water Pump
The garage advised me to get an upraded gasket, but this thread: http://www.andyspares.com/discussionfor ... ead,gasket wanrs against them.
I plan on getting the head skimmed just to make sure, have I missed anything?
Cheers
David

Camshaft and crankshaft oil seals, possibly?
Getting the waterpump gasket off of the block is painful, a window scraper will be very handy.

I've also got a head gasket problem on my 106 1.5D - it's getting smoky and there's oil leaking from the head.
The garage have looked at it and say that if they skim the head and replace the gasket there's no guarantee that it will solve the problem because the skimming increases the compression and this will cause the gasket to fail again; they say this engine is well known for this being a problem.
The gasket may have already been replaced and therefore head possibly skimmed by a previous owner.
Mileage is 65000.
They suggest either get rid of the car or replace the engine.
Is this a known problem on the 1.5D, or are they are erring on the safe side to avoid the risk of them doing the work, and it not solving the problem?
Thanks
John

The garage don't sound over competent do they? They're also wrong in what they're telling you. If the job is done properly then the car will be no more likely to blow it's head gasket than it was before.
What colour is the smoke, John?
Where in the UK are you?

Smoke colour - grey/black, only on hard acceleration, or on load going up a hill. It's not clouds of smoke so you can't see the car behind, but it's enough that I can see it in the rear view mirror, and the oil dropping on the drive is a pain!
I'm in Sussex.

You've got two problems then John.
1. Leak. Rather common, and fixed with a gasket change. There's a fair chance that a skim won't be necessary. You need a garage who will chech the head, rather than just get it skimmed "because thats what they do." My ZX had it the gasket done for the same reason at 55K, no skim and still fine 70,000 later.
2. Smoke. It's normal for the XUD to produce a little smoke that's visible in the headlights of following cars. Don't worry too much about it, but change the air filter, pop in a can of injector cleaner and take the car for a hours run up a motorway using higher revs than normal. i.e. Give it an Italian Tune-Up. The smoke should reduce to almost gone. If not, post back.
Sounds like you need to find a better garage!

Thanks for that, I'll give it a go.
The garage are normally very good - I've been using them for 10 years with a variety of cars (none of them very new!). The problem might be that the partners generally don't get their hands dirty any more, and employ young mechanics to do most of the work. After the Italian tune up I might go back on a Monday or Tuesday when the more knowledgable partner is there and see what he says.
Thanks again
John

OK, the update.
Head gasket replaced, so the oil leak has gone.
Italian tune up done, but the smoke is still there, black when under load, going up hills is worst. It's more than 'visible in the headlights of following cars'
Any suggestions?
thanks

Black smoke is overfuelling. Possibly weak injector pintle springs, but most likely someone has twiddled with the max. fuelling screw on the pump. Twiddle it back down (screw it OUT for less fuel) and all should be well. You will probably find this will affect the idle speed too, which may need to be reset.
